Inside Macintosh: Networking With Open Transport / Part 2 - Open Transport Reference: Chapter 22 - Endpoints Reference / Constants and Data Types

Endpoint Service Types
Open Transport uses the servtype field of the TEndpointInfo structure to indicate the kind of service the endpoint provides. The constant names that Open Transport can return for this field are given by the endpoint service enumeration:
enum {
      T_COTS         = 1,
      T_COTS_ORD     = 2,
      T_CLTS         = 3,
      T_TRANS        = 5,
      T_TRANS_ORD    = 6,
      T_TRANS_CLTS   = 7   
};
